'The is mountedin suiters a, one coacting frame at its extremity meshes with theCarried alsoby that Aend of the shaft e, but inside the frame, isanother pina pinion e3, mounted e on the shaft of the feed-roll E. Thelastnamed shaft is mounted inthe frame inema separator-rch,plleferably-` Y "of rubber or having a rubber periphery, lonorcorrugated. Y The shaft f of said separator-roll is mounted in the sideas shown at d, one end of said inion d. Adjacent to and adjustablerelatively thereto is an idler-roll D', the ends bearing-blocks dz,withcranks on the operated by fingeridler'- roll toward or ICO bers e inthe same manner as is theshaft of ,one of the pressing and passing rollspresently to be described, and since the mounting of the latter. is moreclearly 'shown in vthe drawings further description of the mounting ofthe shaft of said feed-roll E is here omitted. The pinion 2 meshes withan idler-pinion e", carried on the inner face lof one of the framemembers and meshing with a pinion e5, mounted upon the shaft e of one ofthe pressing and passing rolls F, whieh roll is preferab y metallic.Said shaft e `is here shown as the main shaft of the machine, Ithe endsthereof being journaled in the frame members a and passing through thesame, one end of said shaft being provided withthe drivewheelf and theother with a pinion f the function whereof will be presently explained.The pinion c meshes with a pinion g, mount- -ed upon the shaft g ofthepressing and passinfgroll G, which coacts with the pressing and passingroll F. Said shaft g is mounted at its ends in the frame members ainmanner simi.- lar to the mounting of the feed-roll E, this including ateach end the use `of a bearingblock g2, in which. the shaft lend isjournaled and which has sliding movement in an openmg in the framemember and a yielding pressuredevice coactingwith said block andcomprising the'barrel g? andthe spring-pressed plunger g, operatingtherein and tending to force said bearing-block and the shaft endjournaled therein toward the roll F. This provision with regard tospring-pressed coaction of the pressing and passing rolls F G is alsotrue with respect tothe feed-rolls E E.

H designates a deli\'eryroll, havinggpreferably, a rubber-coveredperiphery and mounted upon shaft h., the ends whereof are iournaled inthe frame members a by means of the sliding spring-pressed blockconstruction-just described in connection with the pressing and passingroll G. Mounted upon the shaft of said roll H is a pinion 71.','wliichmeshes with the pinion c5 on the main shaft (if U/ e designate ears,preferably formed integral with the frame members a, and upon thesev isdetachably mounted (see set-screwsl i) a cross-bar if, carrying thesheet guide or buclder l.. Said cross-bar is provided with an"inwardly-projecting web "Z2, to which are secured the parallel guidemembers i3 i". ll`he free end of the latter terminates in proximitytothe periphery of the delivery-roll H, while the correspondiiigend ofthe guide member i vis curved and terminates in proximityto the peint ofeoaction between vthe peripheries of ythe passing and pressing rolls l?G.

i5 designates a sliding stop operating between and extending from edgeto edge of the guide members i. i4. and a'portion of the guideinember iis a i vplate i", secured/to the cross-bar i and hav-- ing an elongatedslot t', through which oper- (.lverlying said stop" ates a screw-stud i'carried b s'aid sto i5 a set-nut i. As will be readily understood,

'moved to any suitable point4 between'the guide members4 i i* and firmlyclamped in proper position, the object of said stop being the guidemembers i i* of a folded sheet fed therein from between the passing andpressing rolls F G. v

'L desi nates a rock-shaft jouinaled at its ends in t e side members aof the frame, one end projecting throu h such frame and being providedwith a cran -arm Z, the end whereof is attached to the connecting-rodZ', running to the crank-arm Z2 of eyeloineter Z3. The

shown in Fig. 2 by means of coil-spring Z4. Mount-ed up'on therock-shaft L and projecting inwardly therefrom are arms m, to the innerends whereof is secured the angular guide-plate M. Said guide-plate, asclearly shown in Fig.- 5, is rovided with the web m',

.tion of the periphery of the roll F and the portion m2 at right angles.thereto and constiedge of a sheet fed between the rolls F and H.Additionally, said guide-plateM is provided with downwardly and inwardlyprojecting lips m, terminatin in close proximity to the peripheryof thero l tional guide-rolls n, each about coextensive 1in length with thedistance between two adjasite-such space. Theends of such guide-rollshaft are mounted in'han ers n', depending fr o'rnvthe main shaft e".Adjaeent' 4to one of the ends so mounted said shaft N is provided with apinion n2, which meshes with the pinion h of thedelivery-roll H. Asclearly shown in Fig. 3, the guide-roll shaft N and sectional rolls 'nthereon operate in close proximity to the peripheryof the deliyerysurein this position by means of'springs as 1L, said springs also serving-tomaintain the pinion'n2 in eoaetion with the inion h Lying directlybelow' the point of coaction of-the sectional guide-roll n anddelivery-roll His the stripper-plate P, secured in any suitable rnannerto the side members ..of the frame. The upper edge of said 'Slate termi-'iiateseither in Contact with or in close proximity tothe periphery' ofthe delivery-roll H, lso as to receive upon its outer surface a foldedsheet fed between said`delivery-roll and said sectional roll. Said plateis provided with an elongatedvertioal slot p, through which works thescrew-stud p on the end of the adand with the threaded portion whereofcoacts to determine the degree of traverse Within substantially para lelwith the coaeting por-v tuting a guide-stop for the advancing (folded)cent lips m3 on the guide-plate Mand'oppojusting thumb-piecep, saidscrew-stud co, acting with a threaded perforation in the de- 'l the stop"i5 may, by reason of said nut i", be l Y crank-arm Z is normally heldin the position lN' designates a guide-roll shaft having s ec- IOO rollH and are maintained by yielding pressettle vwith a longitudinally'flute or corrugated periphery, preferably of rubber. The periph- -ery ofsaid forwarding-roll extends slightly labove the surface of said ways,so as to forward upon the same the folded sheets Vfed thereon. Theextreme end of the bearinglug 1'5 is vyoke-shaped, comprising themembers r r, and loosely journaled in said members so as to havevertical freedom of movenient is a shaft S, which shaft is providedbetween the members rl 7 with the spiral. gear 8, meshing with acorresponding gear s on the extreme end of the forwarding-roll shaft r.The upper end of said shaft is journale in the ends of the yoke s2,secured to the exterior of one of the frame members a, and has keyed orotherwise secured thereto within said yoke the spiral gear e3, whichmeshes with a similar gear s* upon a stub-shaft S5, secured to the saidframe member. 'lhe spiral gear s4 is driven by a pinion s", mounted uponsaid stub-shaft and driven by the pinion f on the main shaft e6. 1t willtherefore be seen that the support R for the inner end of the deliveryapparatus may be raised or lowered (by means of adjusting thumb-piecefr, te.) without interfering with the means for driving theforwarding-roll R2, the .yoke members 1 r and spiral gear Lslicing, asabove stated, free to move upon the shaft T 'il designate are-shapedslots formed opposite each other in the frame members (L a.,y and withinthese slots operates a cross-rod t, one end whereof is provided with ahead t', the other end being threaded and provided with a set-nutsimilar to the nut p2, whereby after said cross-rod t has been moved toany desired position within the slots ,'.l it may be there securelyclamped. Carried by said cross-rod and between the said members of the.frame is the si1pportingvbracket t2, having ears t, to which the ways llt are secured, as shown in Fig. l. Oiorating upon saidways is thesliding block U, movable ,hereover toward and from the s tripperplatel). 1t will therefore be seen that any desired inclination of the wayslt lt may be secured by means of either one or both ,of the twoindependent adjustments herein described. .ln the specilic form of themechanism disclosed the guide-roll n should coact with the upper edge of4the folded., sheets in order to and there y o en a space rearward ofthe stripper-plate lEfor the reception of the next succeeding foldedsheet. Inasmuch as sheets of different sizes are to be folded, it isdesirable that the inner end, whether with or independent of the outerend of the deliveryways, should be adjustable toward and from saidguide-roll n. This is accomplished by the mechanism described, it beingpossible to readily elevate or depress the inner end of the guidewaysand to secure the same in adjusted position by means of the set-nut p2.The outer end of said ways may, if desired, be corres iondingly changedby means of the slots cross-rod t, and supporting-bracket carried bysaid cross-rod.

The operation of the machine has been to some extent explained inconnection with the foregoing descriptiony of the parts. The lowermostsheet is fed from the pile by means of the separator-roll l), buckled,as illustrated in Fig. 3, and passed downwardly to the feedrolls E E,which thereupon grasp the buekled portion and feed the sheet downward tothe pressing and passing rolls F G, after passing through which theadvancing (buckled) edge passes into the sheet-guide l until itsmovement therein is arrested by the stop t, whereupon the sheet is againbuckled and fed to the grip of the rolls l" Il. The advancing (folded)edge strikes against the lips m and operates the rock-shaft li, whichthereuponlreeords the passing of such sheet upon the eyclometer Z. Suchedge is thus guided downwardly between said roll lI and the scctionalroll It and passed to the ways it', the upper edge being moved outwardly(away from the stripper-plate P) by means ol said sectional roll. Thisoperation being co'ntinued, the sheets of the entire pile ariv`successively folded and stacked upon said ways,

. the sliding block U being moved outwardly therefrom by theaccnnuilation of such folded sheets and the action ol' theforwardingroll lii.

l claim as new therein, and desire to secure by Letters Patent, is asfollows:
